Vacuum Tubes Pre-Amplifier PCB | How Vacuum Tubes Work?

High quality PCB prototypes: https://www.pcbway.com 3D & CNC service: https://www.pcbway.com/rapid-prototyp... 🔥I've made a pre amplifier made with 6N1 vacuum tubes. I've designed the PCB and assembled all the components. You have the circuit and PCB below so check all the links. See the test at the end of the video. 🔀LINKS ------------------------------------- Tutorial website: https://electronoobs.com/eng_circuito...
